FIG. 2.
(a) Size distribution of lipid-PLGA hybrid NPs synthesized at different flow rates measured by dynamic light scattering (DLS). (b) Polydispersity index (PDI) of lipid-PLGA hybrid NPs by DLS. (c) TEM images of lipid-PLGA hybrid NPs synthesized at low (41 ml/h) and high (246 ml/h) flow rates. The inserted images clearly show the core-shell structure of hybrid NPs.
